Abstract

Several approaches towards transparent, diverse protection
services at the application layer have been proposed in re
cent years. For diverse protection services, the discovery
of appropriate alternate paths is one of the key issues. This
is also the case for application layer diverse protection ser
vices. In this work1
we introduce a scalable Peer-to-Peer
(P2P) based active signaling overlay network. We use cus
tomized lightweight software agents that are able to dis
cover the targeted diverse paths
in a scalable way, based on active and programmable
architectures (Active Peers). Based on an inherent pseudo
hierarchy in the P2P networkforced by constructionas
well as on Active Peers, we provide a signaling architec
ture that enables the distributed discovery of optimized al
ternate paths (or trees) for transparent application layer di
verse protected services.
